Specification of Letters Patent.

BOTTLE-CAPPING MACHINE.

Patented July 19, 1921.

Application filed June 8, 1920. Serial No. 387,481.

To all 1071,0712 it meg concern: Be it known that LCALVIN L. BEARDSLEY citizen of the United States, residin at Rock Island, in the county of Rock Is and and State of Illinois, have invented certain new and useful Imrovements in Bottle- Capping Machines, which the followingis a speci cation.

j The present invention relates to bottle capping machines and more particularly to that class adapted to be manually operated, as by placing the cap and bottle into operative relation to the machine by hand and manually actuating a lever which forces the cap into sealing engagement with the bottle. The maclnne is particularly adapted for use in connection with the ordinary crimped edge caps such as are used for closiu bottles containing beverages, etc.

The principal objects of the invention are to provide a machine which is simple in construction and assemblage and hence inexpensive to manufacture; which is easy to operate and well adapted to withstand the forces coming upon it incident to use in effectively capping bottles; and a machine which will remaln in good repair for a great length of time by so transmitting the mot-ion imparted manually to the operating lever that friction is considerably reduced.

Other objects and advantages of the invention will appear in the following detailed description taken in connection with the accompanying drawing, forming a part of this specification, and in which drawing:

Figure 1 is a view in central vertical section through a machine embodying the principle of my invention, the operating lever being shown positioned ready for operation and dotted lines indicating the relative position of parts after the lever has been swung to a position for capping of a bottle.

Fig. 2 is a fragmentary side elevation of the machine.

Fig. 3 is a similar View in front elevation.

Fig. 4 is a sectional View on the line 4--4 of Fig. 1.

In the drawings where similar characters refer to similar parts throughout the views, A designates a support; B a die reciprocable with respect thereto and including a stem C slidable in a bore D in support A; E a lever including a cam F carried by su port A and adapted to engage the stem and G a device for coupling the die B to support A and holding the stem 0 in engagement with cam F.

In the example shown, the support is adapted for attachment, as by plate 5 and screws 6, to a wall or upright 7, and includes a relatively long barrel shaped portion 8 provided with the longitudinal bore D. This barrel shaped portion may be connected to the plate 5 laterally thereto as by a web of metal 9. For a purpose to be subsequently set forth it is preferred to provide standards 10 in spaced apart relation projecting upwardly from barrel shaped portion 8, one at each side of the axis of bore D each standard provided with a bearing 11. j The die B is' provided with a recess 12 adapted to receive an ordinary crimped metal cap for bottles (not shown in the drawings) the lower portion of the recess flaring outwardly as indicated at 13 which engages the flared portion of the cap as the die moves downwardly forcin the corrugations into intimate contact with the bottle as is the usual practice. The die has a relatively long stem O reciprocable in bore D, this stem projecting beyond the barrel shaped portion 8 between the standards 10 as indicated at let.

As to lever E and cam F they may be formed integral and pivotally supported by support A, as by a pin 15 received by bearings 11 of standards 10. The throw side 16 is disposed laterally of the longitudinal axis of the lever and adapted for engagement with the projecting portion of stem C so as to force the die downwardly when the lever is swung downwardly as indicated in dotted lines, Fig. 1. It is preferred to dis pose the standards 10 inclined with respect to the vertical so that the axis of oscillation is to one side of the axis of stem C, thus bringing the line of force transmitted through cam F more directly upon the upper portion of stem C, which may be rounded, as indicated at 17, at its head so that the cam will ride more smoothly with respect to and over the stem. The relatively long stem C and barrel shaped portion 8 of support A aid in maintaining the machine in good repair providing a relatively long bearing for the stem during its reci r rocation and the pivotal disposition of the lever E with respect to the stem aids in preventing a lateral thrust which might otherwise cause excessive wear and reduces the liability of the bore D wearing eccentrically.

The device G, in the example shown has the dual function of coupling the die B to support A and yieldably urging the .stem 0 into intimate contact with cam F and may comprise a contractile springlS, having one end portion secured to support A as by having its terminalportion 19 trained through an eye 20 in a lug 21projecting laterally from barrel shaped portion 8; and its other end portion secured, as by screw 22, to the die B. This spring is elongated as the lever moves downwardly and aids in returning the lever E to a normal upwardly projecting position and so yieldably retaining it against downward movement incident to vibration or the force of gravity.

It is to be noted that this spring 18 also permits circumferential movement of the stem "C in its bore D so that it is not absolutely necessary to finish the end portion 14: ot'stem C nor to make the cam surface parallel to the axis of oscillation of lever E in order to get a good bearing since the stem may move circumferentially to accommo date itself to any slight unevenness in the cam surface,'and likewise a slight twist of the die and cap with respect to the bottle may be necessary in the event the cap receiving portion oft'the bottle may be slightly imperfect.

It is to be understood that the drawings and foregoing description are by way of example, the preferred embodiment of the present invention but that the support A may be of that character to rest upon a support, such as a table and that changes in detail may be made without departing from the spirit of the invention as defined in the following claims.

I claim:

1. A bottle capping machine comprising in combination a support, a die including a stem reciproca ble and freely movable circum'iferen'tially, with respect to said support, a lever including a cam, carried by said support, the cam engaging said stem, and a device coupling said die to said support and yieldably urging said stem into engagement with said cam.

2. A bottle capping machine comprising in combination a support, a die including a stem 'reciprocable and freely movable circumferentially with respect to said support, a lever including a cam, carried by said support, the cam engaging said stem, and a contraction spring having one end portion secured to saidsupport and the other end portion to said die coupling said die to said support and urging its stem into engagement with said cam.

in testimony whereof I aflix my signature.

CALVIN L. BEARDSLEY.
